Low Tire Pressure Display
Should this occur, you should stop as soon as possible
and inflate the tires with a low pressure condition
(those in a different color in the instrument cluster
graphic) to the vehicle’s recommended cold placard
pressure inflation value as shown in the "Inflate to
XX" message. Once the system receives the updated
tire pressures, the system will automatically update,
the graphic display in the instrument cluster will return
to its original color, and the Tire Pressure Monitoring
System Warning Light will turn off. The vehicle may
need to be driven for up to 20 minutes above 15
mph (24 km/h) in order for the TPMS to receive this
information.
NOTE:
When filling warm tires, the tire pressure may need to
be increased up to an additional 4 psi (28 kPa) above
the recommended cold placard pressure in order to
turn the Tire Pressure Monitoring System Warning Light
off.
Service TPMS Warning
If a system fault is detected, the Tire Pressure
Monitoring System (TPMS) Warning Light will flash on
and off for 75 seconds and then remain on solid. The
system fault will also sound a chime. In addition, the
instrument cluster will display a "SERVICE TPM SYSTEM"
message for a minimum of five seconds and then
display dashes (--) in place of the pressure value to
indicate which sensor is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring System
Warning Light will no longer flash, and the "SERVICE
TPM SYSTEM" message will no longer display, and a
pressure value will display in place of the dashes. A
system fault can occur due to any of the following:
●
Signal interference due to electronic devices or
driving next to facilities emitting the same radio
frequencies as the Tire Pressure Monitoring System
sensors
●
Installing aftermarket window tinting that contains
materials that may block radio wave signals
●
Accumulation of snow or ice around the wheels or
wheel housings
●
Using tire chains on the vehicle
●
Using wheels/tires not equipped with TPMS sensors
A system fault may occur due to an incorrect TPMS
sensor location condition. When a system fault occurs
due to an incorrect TPMS sensor location, the Tire
Pressure Monitoring System (TPMS) Warning Light will
flash on and off for 75 seconds and then remain
on solid. The system fault will also sound a chime.
In addition, the instrument cluster will display a Tire
Pressure Temporarily Unavailable message in place of
the tire pressure display screen. If the ignition switch is
cycled, this sequence will repeat, providing the system
fault still exists. If the system fault no longer exists, the
“Tire Pressure Monitoring System Warning Light” will no
longer flash and the tire pressure display screen will be
displayed showing the tire pressure values the correct
locations.
Vehicles With Non-Matching Full Size Spare Or Compact
Spare
●
The non-matching full size spare or compact spare
tire does not have a TPMS sensor. Therefore, the
TPMS will not monitor the pressure in the non-
matching full size spare or compact spare tire.
●
If you install the non-matching full size spare or
compact spare tire in place of a road tire that has
a pressure below the low-pressure warning limit,
upon the next ignition switch cycle, the Tire Pressure
Monitoring System (TPMS) Warning Light and a “LOW
TIRE” message will remain on and a chime will
sound. In addition, the graphic in the instrument
cluster will still display a pressure value in a different
color and an “Inflate to XX” message.
●
After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the Tire Pressure Monitoring
System (TPMS) Warning Light will flash on and off
for 75 seconds and then remain on solid. In addition,
the instrument cluster will display a "SERVICE TPM
SYSTEM" message for a minimum of five seconds
and then display dashes (--) in place of the pressure
value.
●
For each subsequent ignition switch cycle, a chime
will sound, the Tire Pressure Monitoring System
(TPMS) Warning Light will flash on and off for
75 seconds and then remain on solid, and the
